Combine like terms
a^2-4a^2=-3a^2
7a^3+11a^3=18a^3
Then put them back together from greatest exponent to smallest exponent
18^3-3a^2-a

What is the correct description for the system of linear equations?
Mkey [24]
The slope of the first equation is -2, you can see it right off.

the slope of the second equation is 2, notice both are in slope-intercept form.

both equations are the equations of a line, so is really just two lines.

because their slope differs, they're not parallel or equivalent, therefore, they lines do meet at some point, and one point only, and therefore, they have 1 solution only.

a system of equations with at least 1 solution,  is a consistent system.

a consistent system with exactly 1 solution only, is not just consistent, but also independent.
